Question

Hcf of two numbers is 12if sum of two numbers is equal to 72 how many pairs of these numbers are possible

Answer 1

Answer:

Step-by-step explanation:

HCF=12

So the numbers can be written as 12a and 12b where a and b are co-prime to each other.

Sum=72

12a+12b=72

a+b=6

So possible values for (a,b) are either (1,5) or (5,1) as a+b=6 and a abd b are co-prime to each other

So the numbers are 12 and 60
